A proton therapy system in Nagoya Proton Therapy Center
Australasian Physical & Engineering Sciences in Medicine, 2016The purpose of this paper is to describe an outline of a proton therapy system in Nagoya Proton Therapy Center (NPTC). The NPTC has a synchrotron with a linac injector and three treatment rooms: two rooms are equipped with a gantry and the other one is equipped with a fixed horizontal beamline.

Annual Review of Biophysics and Bioengineering, 1982
Conventional radiotherapy with high energy photons and electrons has been remarkably successful in treating many localized tumors. However, if tumors are large or are located very close to critical normal structures, it becomes very difficult to deliver a tumoricidal dose to the entire tumor volume without compromising the function of these adjacent ...

Sarcomas are a heterogeneous group of tumors that can occur in a wide array of anatomic sites and age ranges with varying histologies. Proton beam therapy, as compared with advanced x-ray radiation therapy techniques, can substantially lower dose to nontarget tissues.

The technology that is used for the production and delivery of therapeutic proton beams is reviewed. Increased interest in this treatment modality has inspired a new generation of technology development and research into methods that will make proton treatment facilities more widely available (less expensive) and more efficient. Proton beam therapy has

There are two facilities for clinical trials with protons in Japan: the National Institute of Radiological Sciences (NIRS), Chiba, and the Particle Radiation Medical Science Center (PARMS), University of Tsukuba. At the National Institute of Radiological Sciences, patient treatment with the 70 MeV proton beam began in November 1979, and 29 patients ...

Radiology, 1974
Physical, technical, radiological, and clinical status of proton therapy is reviewed. Protons produce effects similar to those of x rays, but dose distribution and range make protons more flexible and useful therapeutically. The ability to confine the major fraction of proton absorbed dose to a designated volume allows the decrease of dose to normal ...

Cancer radiotherapie : journal de la Societe francaise de radiotherapie oncologique, 2017
Proton therapy is an optimized radiotherapy technique. Today, the technical improvement provides reliable machines. The therapeutic indications are clearer even though therapeutic trials should confirm the current guidelines. A better knowledge in radiobiology could be useful if it is integrated in the treatment planning system.

The clinical advantage for proton radiotherapy over photon approaches is the marked reduction in integral dose to the patient, due to the absence of exit dose beyond the proton Bragg peak. The integral dose with protons is approximately 60% lower than that with any external beam photon technique.
